A hydraulic lifting device that grips steel strand cables to raise or lower extremely heavy loads incrementally. Subcontractors use strand jacks for heavy lifts on modules, bridges, and offshore structures. They are often mobilised by specialised rigging crews under a separate lifting subcontract.
Strand Jack
Related Terms
Tide Gate
IndustryA one-way valve or flap gate that allows water to drain freely but prevents backflow from rising tides or high water levels. Subcontractors working on coastal or waterfront sites must account for tide gate locations when planning drainage, excavation, or utility work. Ignoring these structures can cause flooding, schedule delays, and scope changes.
Pre-Feed (pre-Front End Engineering and Design)
IndustryAn early project phase where owners assess technical and commercial feasibility before committing to full design. For subcontractors, it signals potential future scope but rarely includes direct field work. Winning study contracts at this stage can position your company for larger awards later.
Grid Interconnection
IndustryThe process of connecting a power generation asset to the public electrical grid. For subcontractors, it triggers specific commissioning milestones, inspections, and sign-offs. Delays in interconnection approval can directly impact project timelines and invoicing.
Midstream Consolidation
IndustryThe merging or acquisition of pipeline, processing, and storage companies into fewer, larger operators. For subcontractors, this can shift approved vendor lists and contract terms overnight. Expect longer onboarding processes and tighter pricing pressure from consolidated procurement teams.
BOPD (Barrels of Oil Per Day)
IndustryA measure of a well's or facility's daily oil production output. Operators use BOPD targets to schedule field service work, so higher rates often mean more frequent maintenance contracts and crew rotations. Subcontractors may see BOPD thresholds written into service agreements to trigger additional scope.
Triplex Mud Pump
IndustryA three-cylinder reciprocating pump used on drilling rigs to circulate drilling fluid down the wellbore. Subcontractors are often hired to operate, maintain, or repair these high-pressure units. Reliable pump performance is critical — downtime directly impacts rig schedules and your contract standing.
